Ekovatmeas provides a series of instruments, probes and accessories, which are specially designed for transformer applications to realize on-line monitoring of the internal temperature of oil immersed power transformers. The optical fiber temperature monitoring system based on gallium arsenide technology allows you to fully understand the advantages of optical fiber sensing technology, and can provide accurate, reliable and timely internal temperature measurement of the transformer; The transformer temperature probe is specially designed to be perfectly compatible with the transformer manufacturing process, while fully considering the convenience of installation. Experience has proved that the temperature calculated by the traditional simulation model may deviate from the temperature measured directly by the optical fiber temperature measurement technology. The hot spot temperature directly measured by optical fiber technology is the benchmark for understanding the temperature rise.

TOTF oil immersed transformer winding hot spot optical fiber on-line monitoring system is a temperature measurement system developed based on the principle of fluorescence temperature measurement, which can be applied to oil immersed transformer winding hot spot, GIS equipment internal hot spot, gas insulated high-voltage switch internal hot spot temperature monitoring, etc. The system has the characteristics of self diagnosis, fast temperature measurement speed and high accuracy; And the fluorescent optical fiber sensor has mature technology and good consistency; The temperature information of each hot spot can be monitored online and displayed in the local display system and the background data terminal in real time.

Switch cabinet, box type substation, bus cable bridge, etc. are the most important components of electrical equipment. Under the working conditions of high voltage and high current for a long time, its dynamic and static contacts, bus joints, cable joints, etc. are prone to surface oxidation corrosion, loosening of fastening bolts, aging of contacts and connections, etc. these problems will lead to increased contact resistance, temperature rise and electrical safety accidents. TOSC electric hot spot fluorescent optical fiber temperature on-line monitoring device uses advanced fluorescent optical fiber temperature sensor technology to provide dynamic, real-time, safe and accurate "hot spot" temperature information of equipment operation, prevent sudden safety accidents caused by equipment overheating, and realize the intelligent mode transformation of equipment from "regular maintenance" to "condition based maintenance".
